WHI FFLETREE ATTA-CH MEN-T.

SPECIFICATION forming part of Letters Patent No. 278,258, dated May 22,1883. ApplicatioufiledMarchl, 1883. (NomodeLl To all whom it may concernBe it known that We,-LEONARD STEVENSON I and WILLIAM B. J AOOBS,citizens of the United States of America, resi'ding at Solon,'in the usethe same, reference being had to the accom-,

county of Leelenaw, and atTraverseOity, county of GrandTra'verse,respectively,in the State of Michigan, have invented certain new and Iuseful Improvements in Attachmentsfor Whiffietrees; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and panying drawings, and to letters or figures ofreference marked thereon, which form a part of This invention relates toineans for protect y in g the bark of orchard trees from abrasion by 1 fthe ends of whifietrecs used on plows and other implements employed incultivating the ground.

I It is well known that even the niost careful drivers are liable toallow their whifdetrees to jeorne in contact with the trees whencultivat- 111g an orchard, and a very great injury he quently results tofruit trees from this cause.

With a view to preventing such injury our invention consists in a novelattachment for Yes is a longitudinal section,

trating the connection of trace-tugs and whiffletrees, which will behere inafter particularly described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view of a horse hitched to aplow'by means of a whiffletree and tugs provided with our improvements.Fig. 2 is a top view. Fig. 3

illustrating our improvement. Fig. 4 is a perspective view, illusthebelt with the tug. Fig.5 is a perspective view of the pulley by thewhiftletree, Fig. 6 is a B is the rear portion and 0 the front portionof the trace-tug,

1. the front portion being attached to the harness in the usual mannerand extended rearward .5

through a narrow box, D, into which also extends the front end of therear portion. The

rear end of the front portion has attached to it a metallic plate, E,bent at its rear end to form a hook, e, which projects toward the rearportion of the tug, and is of such extent that 5 it will bind said rearportion against the inner wall of the box D when the rear end of saidportion is drawn into said box. A convenient adjustableconnection isthus made between the two portions of the trace-tug, and by the samemeans the adjustment of the box D is effected for the purpose which willbe presently explained. From the outer side of the box D projects acasing, d, between the upper and of thewhiftletree and each of the tugsbeing connected by belts in the same manner.

In hitching up the horse the box D is moved forward until the belt I istightened, the rear end of the front portion of the tug being firstdrawn slightly rearward out of the box. After the belt is tightened thefront portion of the tugB is correspondingly tightened and insert edinto the box, and the front portion, 0, is then drawn inward, so thatthe hook 6 will bind the rear portion of the tug. The two end attachments being thus adjusted, the hitching up is complete.

It will now be observed that it'- the belt I comes in contact with atree it will be moved longitudinally on its pulleys and will not deleteriously rub the bark, and as the from abrasion by the end of thewhiffletree.

Having now fullydescribed our invention,wewish it to be understood thatwe do not confine plow pro- 8 grosses the moving belt will guard thetree ourselves to any particular construction of the c tug proper, as itis obvious that a pulley may be connected with any ordinary tug or tracechain for supporting the forward portion of a belt passing rearwardlyaround a pulley on a ,whiffletree. Nordo weconfineourselves to any ofthe precise details shownin our drawings,

but reserve to ourselves the right to vary the same in any desiredmanner without departing from the essential principle of our invention.

What we claim is 0 1. The herein-described attachment for a .tug andawhiffletree, consisting of a pulley' mounted in suitable bearingsadapted for attachment to a trace-tug, a pulley mounted in suitablebearings adapted for attachment to the end of a Whiffletree, and a beltarranged to connect said pulleys, substantially as and for the purposeset forth. 7

2. Thefcombination, with a whir'fietree and trace-tug, of a pulleymounted at the end of the whiffletree, a pulley mounted intermediatelyon the trace-tug, and an endless belt connecting said pulley,substantially as described.

3. The combination, with the \vhiffletree A, bracket g, and pulley h, ofthe tug B, adjustable box D, having casing 61- projecting therefrom, thepulleyf, mounted in said casing, and p .the belt I, passing around bothof said pulleys, substantially as described.

graces 4. The combination, with the whiffletree A, having pulley hmounted thereon, thebox D, having the pulley f supported thereby, andthe belt 1', connecting said pulleys, of the tug composed of the forwardportion, 0, passed rearwardly through said box, and provided withclutch-plate E, and the rear portion, B, having itsforward end arrangedfor insertion .into said box for engagement by said clutchplate,substantially as described.

In testimony whereof We affix our signatures in presence of twoWitnesses.
